QuestionQuestion 9
Find the area and perimeter for parallelogram $A B C D$ with vertices $A(-3,4), B(2,4), C(4,-3)$ and $D(-1,-3)$ . Round to the nearest tenths if necessary. Perimeter $=$ $\square$ units
Area $=$ $\square$ units squared Question 10
The coordinate 3 has a weight of 1 , the coordinate 5 has a weight of 3 , and the coordinate 9 has a weight of 2 . Find the weighted average. Question 11

Studdy Solution
Simplify the weighted average calculation step-by-step: $\text{Weighted Average} = \frac{3 + 15 + 18}{6} = \frac{36}{6} = 6$
Solution: Perimeter $=$ $10 + 2\sqrt{53}$ units
Area $=$ $35$ units squared
Weighted Average $=$ $6$
